Specification of Letters latent.

Patented Jan. 18, 1910.

Application iled June 24, 1998. Serial No. 440,160.

To all whom 'it may concern:

Be it known that I, WILLIAM E. Bacoli, a

Mountain avenue, NorthL Plainfield, in the county of Somerset and Stateof New Jersey, have invented new and useful Improvements in Turnbucklesor Couplers, of which the following is a specication.

buckle is .illustrated in M invention relates to 'improvements in coupings, or turnbuckles, particularly adapted :for use in the construction'of portable buildings of the character for which I'have obtainedLetters Patent of the United States No. 638,494, dated Dec. 5, 18-99. Insuchprior constructions the abutting sections of the buildings areprovided with bolts the heads of whichare coupled together by means ofslotted, or U shaped, pieces adapted to be slipped over the heads of thebolts after the sections are set in place.

I have found in practice that diiiiculty is experienced in always gettinthe adjacent sections in line, because the bo ts in the abuttin sectionsof the construction shown.in sai patent are out vof alinement. There isalso the diiiiculty in using the couplings employed in my formerconstruct-ions that because, owing to the eccentric location of thebolts, each of the bolts joined by a coupling has to be turnedseparately; the labor is further increased by the fact that the wrenchemplo ed upon the heads of the bolts can be mote through only acomparatively small an e.

desirable form of m improved turne accompanying drawin in which thereference characters of the dgescription indicate the correspondingparts in the di'erent figures.

Figure 1 is a horizontal section of a por-` tion of two adjoiningbuilding-sections showing a desirable employment of my invention. Fig. 2represents a vertical section of corresponding parts of the building. Fi3 shows an end view of my invention and ig. 4 is a perspective view ofmy coupling with portions broken away.

In my im roved form of coupling the` of the coupl' the coupling may berotated through a rigide angle with a single movement and with aconsiderable-reduction in the time and labor required for the erectionof the buildin To this end I form my coupling A as s own in the drawingswith a central recess 2 adapted to receivethe heads 3 of the bolts 5,which are arranged in aline- Inent with their heads adjacent and theirShanks outwardly extending through slots 6 in the ends of the .couplingAs best shown in Fig'. 4, this central recess 2 is merely of sufficientsize vto admit the heads arranged square and parallel, whereby they areprevented from turning within the coupling.

In the application of my coupling to a portable building construction asshown in Figs. 1 and 2, the bolts 5 are arranged one in either sectionin such alinement, with their heads projecting sufficiently from the,faces of the vertical joists 10 to admit the application of thecoupler 1. Nuts 12 are carried on the ends of the bolts which arereversely screw threaded at 13, .the said nuts being arranged in sockets14 in the horizontal beams 15. Other parts of the building sectionsshown are inside and outside finishing boards 18 and 19; verticaltlling-strips 20 to close the space between the sections when. they arein place; and 22-22 are blocks arranged between the sections above andbelow* the turnbuckle to take 'the strain of the clamping.

It is obvious that my improved coupling may be employed for variouspurposes other than in. the construction of portable buildings and formany situations where the ordinary right and left hand turnbuckle cannotbe em loyed owing to the limitations of vspace avai able.

Havi fully described my invention, what Inaim is,- Y 1. A coupler for atarnbuckle having opposite forked ends adapted to be inserted over theShanks of bolts and to receive between them the bolt-heads arranged adjacent, and having integral connecting pieces connecting the ends, saidconnecting pieces bein spaced to receive between them the bolteads to beheld in parallel `relation thereby.

2. In a turnbuckle the combination with reversely screw-threaded boltshaving their heads set ad'acent and having nuts on the screw threa edbolt ends, of a detachable coupler adapted to be inserted over the boltheads to prevent their turning therein, said coupler adapted to theapplication of a suitable wrench.

3. In a turnbuckle the combination of reversely screw-threaded boltshaving their heads set adjacent, of a detachable coupler adapted to beinserted over the bolt heads, said coupier being provided with oppositeforked ends fitting over the bolt shanks and formed with integral sideconnecting l`pieces, said connecting pieces spaced to receive betweenthem the bolt heads to be held in parallel relation thereby.

4. In a turnbuckle the combination of reversely screw threaded boltsarranged in alinement and having their heads set adjacent, of a couplerhaving a central recess for the insertion of thebolt heads, said recessbeing formed to retain the bolt-heads in parallel relation, and slots inthe coupler end for the bolt shanks.

este@ 5. In a turnbuckle the combination of reversely screw-threadedbolts having their heads set adjacent, of a cylindrical couplingpieceadapted to be inserted over the bolt heads said coupling-piece beingprovided with opposite forked ends fitting over the bolt shanks andformed with opposite integral side connecting pieces between said forkedends, said connecting pieces being spaced to receive between them thebolt heads to be heldl in parallel relation thereby and to permit theapplication of a. suitable wrench to the coupling-piece.

In testimony whereof I have signed my name to this specification in thepresence of two subscribingP Witnesses.
